AGON- -POLE.

SPECIFICATION forming part of Letters Patent No. 316,671, dated April 28, 1885.

Application filed March 18, 1885.

To all whom it may concern:

Be it known that I, NnLsoN- E. SPRING- STEEN, of Detroit, in the county of Wayne and State of Michigan, have invented new and use ful Improvements in Attachments to Wagon- Poles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to new and useful improvements in the construction and operation of wagon-pole irons, or attachments to wagonpoles of that description in which neck-yokes are employed to support the end of the pole when in use.

The invention has for its object the prevention of the accidental displacement of the neckyoke, thereby avoiding the accidental dropping of the pole, and to furnish means as well by which a leading-team may be attached to the end of the pole, as more fully hereinafter described.

Figure l is a vertical longitudinal section through the front end of the wagon-pole, showing the device in position to receive the neckyoke ring. Fig. 2 is a similar figure showing the neck-yoke ring engaged with the tongue and locked against accidental displacement. Fig. 3 represents the front edge of the holdback-iron, showing the socket in the end thereof to receive the locking-bolt.

In the drawings, A represents the holdbackiron, which may be inserted and secured in the tongue in any of the known ways. This holdback-iron terminates at its free end in a socket, a. B is a semicircular plate, having a slot, 6, cut therein, through which the bolt or pivot-pin 0 passes. O is a locking-bolt in the form of a curved hook projecting from and cast or formed, preferably, integral with the plate B. D is a recess to allow the plate and locking-bolt to partially rotate upon the pivot-pin 0. These devices may be let into a wooden wagon-tongue, or they may be employed with a pole-socket, such as is usually secured to the front end of a light carriagepole.

(No model.)

In practice the plate and locking-bolt are thrown into the position shown in Fig. 1 preparatory to engaging the neck-yoke with the tongue. As this is done the neck-yoke ring impinges against the projecting and cutaway part of the plate and forces it to partially rotate upon the pin, thereby throwing out the locking-bolt, the free end of which engages in the socket in the end of the holdback-iron, where the weight of the neck-yoke upon the then rear end of the plate will hold it in place. This forces the opposite and beveled end of the locking-bolt to rest upon the edge of the recess. Aring engaged with the locking-bolt will afford the means of securing a leading-team to the pole, and this additional team will draw down and forward, thereby tending to hold the pole more steady.

To remove the neck-yoke, the operator will push the plate slightly to the rear by so much as the length of the slot in the plate by pressing againstthe end of the locking-bolt near its junction with the plate, where the removal of the neck-yoke will cause the plate to partially rotate and assume the position shown in Fig. 1.

It will be noticed that there is no spring to compel the locking-bolt to perform its func tions, but that gravity is relied upon, so as to compel the bolt to lock the parts together.

What I claim as my invention is- 1. In combination with a wagon-pole having a holdback iron or stop and a rotating hook constructed and arranged with a pivoted plate to engage with a socket in the end of said holdback-iron, substantially as and for the purposes described.

2. A wagon-pole attachment, consisting of a holdback iron or stop having a recess formed in its free end, a semicircular plate having an elongated slot and supported upon a pivot pin or bolt and carrying a locking-bolt, constructed and operating substantially as and for the purposes specified.
